Bar end shifters for your clip on bars will mean you don’t need to move around coming on and off the bars when you need to change up a gear for that extra push, or let your legs spin up a gradient. Then best shifters will be lightweight and aerodynamic, but you also want to select a shifter that fits with the natural angle of your hand. We’ve got plenty of options from the likes of SRAM and Shimano to meet your needs, and your budget.
